How Much House Can I Afford?

“How much house can I afford?” is usually one of the first questions people ask when they begin thinking about buying, and it sounds like it should have a fairly simple mathematical answer. If you earn this much money, you should be able to spend this much on a house.

Unfortunately, mortgages are not quite that tidy.

Your income is certainly part of the equation, but a lender is looking at your larger financial picture. Your existing monthly debts, available savings, credit profile, loan program, interest rate, down payment, property taxes, homeowners insurance, and other housing expenses can all affect what you qualify for. Then there is another part of the conversation that is just as important, which is how much you actually feel comfortable spending.

Those two numbers are not always the same.

What a Lender Means When They Talk About Debt-to-Income Ratio

One term you will probably hear during the mortgage process is debt-to-income ratio, or DTI. In simple terms, it compares certain monthly debt obligations with your qualifying gross monthly income.

Imagine two people who each earn $90,000 a year. One has very little debt, while the other has a large truck payment, student loans, and monthly credit card obligations. Their incomes are identical, but the amount of additional monthly debt they may be able to comfortably take on can look very different.

That does not mean you need to pay off every debt before applying for a mortgage. In fact, I would not recommend moving large amounts of money around or paying off accounts solely because you assume it will help without first talking with your lender. Sometimes paying down a particular obligation can make a meaningful difference. In other situations, keeping those funds available for your down payment, closing costs, or savings may make more sense.

This is where looking at the actual numbers becomes much more useful than following a generic rule you found online.

Your Home Price Is Only Part of Your Monthly Payment

One of the easiest mistakes to make while browsing homes is focusing entirely on the listing price.

If two houses are each listed for $450,000, it is natural to assume they will cost roughly the same amount each month. That is not necessarily true.

Property taxes vary by location and property. Homeowners insurance can vary. One property may have HOA dues while another does not. Your mortgage may include mortgage insurance depending on the financing and down payment. All of those expenses can affect the total monthly housing payment.

Interest rates matter too. The rate on your mortgage affects the principal and interest portion of the payment, which means the amount of home that fits comfortably within your monthly budget can change as rates change.

This is one reason I encourage buyers to think about their target monthly payment in addition to their target home price. If you tell me that you would really like to keep your total housing payment around a certain amount, we can work backward and look at realistic scenarios.

Just Because You Can Qualify for It Does Not Mean You Have to Spend It

This may be the most important part of the entire affordability conversation.

Your mortgage application does not know everything about the life you want to live.

It does not know that you like taking two vacations every year, that your kids play expensive sports, that you are hoping to start a business, or that you simply sleep better when there is plenty of money left in the checking account at the end of the month.

Qualifying for a larger mortgage does not obligate you to take one.

I would much rather have a buyer tell me, “I know I could qualify for more, but this is the payment I want to stay around.” Now we have a useful boundary to work with.

We can compare different home prices, down payments, and loan options and see what actually fits. The goal is not to win a contest for the largest possible pre-approval. It is to buy a home that works with the rest of your financial life.

Once you understand both what you may qualify for and what you are comfortable spending, the home search becomes much easier to navigate.

Home affordability and mortgage qualification depend on individual borrower circumstances, current loan terms, property expenses, and applicable loan guidelines.
